The Verdict: Committees Rule Supreme
While all three methods play important roles in parliamentary democracy, committee scrutiny emerges as the most effective way to hold government accountable. Unlike the Lords, committees include members from different parties who actively challenge each other's views.
Unlike Commons questions, committees aren't dominated by government supporters asking easy questions. The cross-party membership ensures genuine scrutiny happens, while specialist focus means MPs actually know what they're talking about.
Committees combine the best elements of both other methods: they offer specialist expertise like the Lords, plus direct questioning opportunities like PMQs, but without the major weaknesses that limit those systems.
Key Point: The combination of cross-party membership and specialist expertise makes committees the government's toughest critics.
Of course, no system is perfect - the government can still control what gets published and when. But overall, if you want to see politicians really holding the government's feet to the fire, parliamentary committees are where the action is.
The beauty of this system is that it gives opposition parties genuine power to challenge government decisions, ensuring that democracy doesn't just mean "winner takes all" after elections.
